Muhtasari	The NEO PI-R is a comprehensive 240-item self-report personality assessment that measures five major personality dimensions and thirty lower-order facets. Developed by Paul Costa and Robert McCrae in the early 1990s, it operationalizes the Five-Factor Model of personality—one of the most empirically validated trait taxonomies in psychological science. The measure has become the gold standard for personality assessment in clinical, research, and occupational settings.	The Dark Triad Personality Scale measures three socially aversive personality traits: narcissism (entitlement and exploitativeness), Machiavellianism (manipulativeness and strategic lying), and psychopathy (callousness and thrill-seeking). Developed by Delroy Paulhus and Kevin Williams in 2002, and later operationalized in brief forms like the Short Dark Triad (SD3) by Jones and Paulhus in 2014, the Dark Triad construct has become standard in personality psychology for assessing antagonistic, self-centered, and deceitful traits. The scale enables research on personality pathology, workplace toxicity, and evolutionary psychology.
